Subject: [PATCH] Remove external function declarations
We need to redeclare functions that we already have.
This causes issues with recent toolchains:
init.c:100:14: error: redeclaration of 'getcwd' must have the 'overloadable' attribute
extern char *getcwd ();
^
/build/amd64-generic/usr/include/bits/unistd.h:158:8: note: previous overload of function is here
__NTH (getcwd (char *const __clang_pass_object_size __buf, size_t __size))
^
And also reduces the number of build warnings.
This forked repo does the same thing in this (large) cleanup patch:
